. clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to wire tying machines, and has for its object to provide a mechanism which will be comparatively in expensive to manufacture and more eflicient in action than those heretofore proposed.

3 With these and other objects in view the invention consists in the novel details of construction and combinations of parts more fully hereinafter disclosed and particularly a pointed out in the claims- This case 1s a continuation of my copending application #250685, filed .August 20, 1918, and entitled Wire tying machine.

Referring to the accompanying drawings forming a part of this specification in which like numerals designate like parts in all the views Figure 1 is a diagrammatic plan view of a machine made in accordance with this invention;

Fig 2 is a side elevational view of the parts shown in Fig. 1;

Fig. 3 is a view taken on the l1ne 3-3 of Fig. 4:,

Fig. 4 1s a view taken on the line 4-4 of Fig. 2, looking in the direction of the arrows; and I Fig. 5 illustrates the twisted knot made by this invention.

.1 indicates one section of the metal frame work, 2 the other section thereof, and 3 and 4, flanged members rigid wlth said sections by which the latter are secured together as by the bolts 5. The section 1 has the upturned lugs or members 6 and 7 through "which pass the main operating shaft 8, and

which shaft also has a bearlng 1n {the flanges"- 3 and 4 as shown. Said flanged members 3 and 1 are hollowed out to accommodate the .drivin pinion 9 having the hub 10 journaled in said members 3 and ,4, and rigld with th s af Sa p nion 9 m hes with lug or journal 6. 1i.

- lows.

the wire twisting pinion 11 provided withv the hub 12, also journaled in said members 3' and 4. Said hub 12 has the hollowedvout slotted spaces 13 and 14. on each side of the p mon 11, and the latter is provided with the w 1re twlst ng slot 15, as will be more fully disclosed hereinafter. As will be clear from Figs. 2, 3 ands, the flanged members 3 and 4 are respectively provided with the slots 16 and 17 whlch extend outwardly beyond the slotted pmlon 11 and which are wider than is the slot 15 for a purpose that will presently. appear.

The section 2 of the frame work is providedwith the boss 18 which is slotted as at 19 to receive the wire and the upper portlon of which is threaded to receive the clampmg screw 20 provided with the hand actuated means21, as'shown. The lower end 22 of sa1d. screw20'is flat and of such dimenslons as w1ll clamp only one strand of the wire, as will be clear from Figs. 1, 2 and 3. Said section 2 is also provided with a rear extension 24, having a flat under surface v 25, which serves as a means to steady the machine during the twisting operation, as will presently appear. .Near the slot 19 in the boss 18, said section 2 is providedwith the pins or posts 26, which are separated by, a dlstance substantially equal to the diameter of the .wire to be used in the machine, and

the section 1 is provided with a boss or an enlargement 28 havin two posts 29 similar to the posts 26 and li ewise separatedby a distance slightly greater than the diameter of the wire to be twisted. Said enlargement 28 is rigid with'the ln 7 which terminates in the upright boss 30 m which is journaled for rotation the slotted wire tensiomn member .31, having the operating han le 32. Said frame section 1 is also-provided with the flat under surface 33 forming a continuation of the surface 25 of theframe section 2. The shaft 8 is provided with the register/with the index or mark 37 on the I sgone end 40 of passes the bight 41 between the posts 26, into the slots 17, 15 and 16, between the posts 29, behind the tensionin member 31, over the top 42 of the box 4 own the side, under the bottom, and up the other side back to the slot between the posts 29, whereupon the bight 44 of the wire also passes into the slots 17, 15 and 16, between the posts 29,

and into the slot 45 of the tensioning post 31. The box being thus encircled by the wire 46, the handle 32 is operated to turn Said post 31' and thus wind up the bight 44 thereon. This winding operation tensionsthe wire to anydegree desired, whereupon,

while the wire: is still under tension, the.

handle 34 is operated to turn the shaft 8, the gear inion 9 and the slotted gear pinion 11. The ights 41 and 44 being held against rotation by the slots between the posts 26 and 29, the slots 17 and 16, and the hollow spaces l3and: 14 in the hub 12 being of sufficient dimensions to ermit a free rotation of said bights, whlle the slot 15 like those between said posts being too narrow for such rotation, it results that a 'turnin of the inion 11 in the manner describ will twist together said bights 41 and 44 while under f tension, and into the knot shown in Fig. :5.

- Afterthe twisting operation, the tensioning post being vertically slidable in the boss 30, said post is raised until the wire wound therearound during the tensionin operation, strikes the underside 50 of sai boss 30, whereupon said wire is forced off said post'l3w At the same time, the end 40 is released from-the clamping screw 20, and then the entire machine may be slid out from under saidwire.

, An important feature of the invention resides in theoonstruction' by which the two sections of the frame 1 and 2 have smooth bottoms 33 and 25, which lie flatdown upon Y the top-42 of the box, so that the bights 41 and 44 of the wire likewise lie comparation resides in the fact that the section 1 extends a considerable distance along the top of the box away from the twisting ears or pinions 9 and 11, so that the hand e 34 may be located beyond the extreme edge'of the box and thus may be operated along down pp ite the vertical side of the box without'coming in contact with the top' thereof. iThis enables the machine to be made of a lighter construction than would be otherwise the case.

Another important feature of the invention resides in the fact that the extension 24 is disposed in a position at a considerable an 1e to the section 1 of the frame work, an it extends aconsiderable distance from the twisting slot 15 so that while the levers 34 and 32 are being operated, said extension 24 acts as a means to prevent the machine from ti ping. In other words, a comparatively s ight pressure by the hand upon the extension 24 holds the machine firmly in position during the operation thereof.

It will now be clear that by providing the ribs on the frame work as shown, the latter may be made of a minimum lightness, and by disposing of the parts as disclosed, it may be made of a maximum efiiciency to the end that the bights of the wire may be readily and rapidly twisted together and the machine disengaged from the finished tie in a minimum of time.

By providingthe indices 36 and 37, the operator may turn the handle 34 any desired number of times, and thus put into the bights 41 and 44 any desired number of turns, and yet be sure, at the end of, the twisting'operation, that the slots 15, 16 and 17 will all be in register. It is obvious that unless said slots are stopped in register with each other that it would not be an easy matter to get the wire out of the twisting mechanism at the end of the tyin operation.

It is obvious that those shined in the art may vary the details of construction, as .well as the arrangements of parts without departing from the spirit of the invention, and

therefore I do not wish to be limitedtto the above disclosure except as may be required by the claims. 1 What I claim, is 1.
